What will be the output of the following C# code?

class Program
{
    static void Main(string[] args)
    {
        int i = 5;
        int j;
        method1(ref i);
        method2(out j);
        Console.writeline(i + "  " + j);
    }
    static void method1(ref int x)
    { 
        x = x + x;
    }
    static void method2(out int x)
    {
        x = 6;
        x = x * x;
    }
}
